Description

ABSTRACT:
A dispensing bag for particulate matter is closed at one end by a two layer closure formed by an openable outer closure, and an inner dispersion panel with apertures of suitable size therethrough. Opening the outer closure exposes the apertures in the dispersion panel and permits particulate matter to be dispensed therethrough. The bags may be conveniently mass produced from sheet material, such as flexible plastic, in the form of a continuous strip or flattened tube, by appropriate cutting, folding, and joining operations. The invention provides an inexpensive container from which particulate matter may be conveniently dispensed in controlled fashion, and which resists accidental opening and spillage.
